Isolated Splitter and signal Converter DAT5022 DIP Switch programmable.

GENERAL DESCRIPTION

The Isolated splitter converter DAT5022 is designed to provide two output voltage or current signals proportional to the value of the input signal.

The user can program the input and outputs ranges by the DIP-switches available after opening the door located on the side of the device .

The regulation of zero and span values is made by the ZERO and SPAN potentiometers located on the top of device.

The DAT5022 is accurate to 0.1% full scale and has less than 0.01%/'f thermal drift.

The DAT5022 provides on the input side an auxiliary supply source to power up a loop. It also provides an auxiliary power supply source on the output side so both active and passive loads can be connected.

It is possible to set the minimum and maximum values of the input and output ranges in any point of the scale, keeping the minimum span shown in the table below.

The DAT5022 is isolated between the power supply and the input/output to 2000V, eliminates the effects of any ground loops and allows the use of the transmitter in heavy environmental conditions found in industrial applications.

The DAT5022 is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.

The DAT5022 is housed in a plastic enclosure of 12.5 mm thickness suitable for DIN rail mounting in compliance with EN-50022 and EN-50035 standards.

USER INSTRUCTIONS

The converter DAT5022 must be powered by a direct voltage included in the 18 V to 32 V range. The power supply must be applied between the terminals Q (+Vdc) and R (GND).

The output 1 connections must be made as shown in the section "Output 1 connections".

Voltage output: between the terminals L (Out1) and G (Out1 GND); passive current output: between the terminals L (Out1) and G (Out1 GND) for the sink currents; active current output : between the terminals I (Aux supply 1 ) and L (Out1) for the source currents. The output 2 connections must be made as shown in the section "Output 2 connections".

Voltage output: between the terminals F (Out2) and H (Out2 GND); passive current output: between the terminals F (Out2) and H (Out2 GND) for the sink currents; active current output : between the terminals E (Aux supply 2) and F (Out2) for the source currents. The input connections must be made as shown in the section "Input connections".

Voltage input: between the terminals N (Input V) and P ( Input GND ); passive current input: between the terminals O (Input I) and P ( Input GND ) for the sink currents; active current input for the source current ( for example coming from a passive transmitter) : between the terminals M (Aux supply) and O (Input I).

The configuration of input and output ranges is made by DIP-switches; the output channels can be set independently (refer to the section “Input ranges table” and “Outputs ranges table”).

After the converter configuration, it is necessary to calibrate it using the ZERO and SPAN regulations; this operation is illustrated in the section “DAT 5022: Configuration and calibration”.To install the device refer to the section “Installation instructions”.

INSTALLATION INSTRUCTIONS

The DAT 5022 device is suitable for fitting to DIN rails in the vertical position. For optimum operation and long life follow these instructions:

When the devices are installed side by side it may be necessary to separate them by at least 5 mm in the following case:

- If panel temperature exceeds 45°C and at least one of the overload conditions exists.

- If panel temperature exceeds 35°C and at least two of the overload conditions exist.

If all the overload conditions exist.

Overload conditions:

- Use of input auxiliary supply (terminal M).

Use of output 1 auxiliary supply (terminal I ).

- Use of output 2 auxiliary supply (terminal E ).

Make sure that sufficient air flow is provided for the device avoiding to place raceways or other objects which could obstruct the ventilation slits.

Moreover it is suggested to avoid that devices are mounted above appliances generating heat; their ideal place should be in the lower part of the panel. Install the device in a place without vibrations.

Moreover it is suggested to avoid routing conductors near power signal cables (motors, induction ovens, inverters, etc...) and to use shielded cable for connecting signals.

Warning: when the voltage input (terminal N) is not used, it is suggested to not connect cable to it or connect the terminal N to the terminal P.

CONFIGURATION

1) Calculate the difference between the maximum and the minimum value of the input range (Span).

2) Refer to the “ Input ranges table " and determine in the column " SPAN" the position where the calculated value is included, then referring to the position obtained determine in the column “ZERO”, the line in which the minimum value is included . In the correspondent line is shown as to set the DIP-switches .

3) Set the DIP-switches as indicated .

4) Connect on input a 3 wire Pt100 simulator programmed to supply the maximum and minimum values of the input range or a fixed resistor of the same values.

5) Set the simulator at the minimum temperature or to connect a fixed resistor correspondent to the minimum value.

6) By the ZERO potentiometer calibrate the output at the 4 mA value.

7) Set the simulator at the maximum temperature or to connect a fixed resistor correspondent to the maximum value.

8) By the SPAN potentiometer calibrate the output at the 20 mA value.

9) Repeat the operation from the step 5 to the step 8 until the output value will be correct ( 3 attempts typically required).

Configuration ex. : in: 4÷20 mA out 1: 0÷10 Vdc, out 2: 4÷20 mA.
Input switches configuration (SW1): On, Off, On, Off.
Output 1 switches configuration (SW2): Off, On, Off, Off, Off.
Output 2 switches configuration (SW3): On, Off, Off, On, On.
